This'invention relates to an-oiling apparatus particularly adapted for use in connection with edger arbors but'it is to be understood that the apparatus may be used in e any connectionfor whichit is found to be applicable.

The principal object of the invention is to provide, in a manner as hereinafter set forthya device by means'of which oil may le -be advantageously applied to an edger arbor.

by the operator of the edger, in regulated amounts.

A further object of the invention is to I provide a device for the purpose aforesaid whereby the oil maybe applied to the arbor in the form. of a spray and in a predetermined quantity.

A further object of the invention is to prof vide a device for the purpose aforesaidwhich as simple in constructlon, positive 111 opera- 131011, efficient in ltsintended use,wh1ch may be readily installed in connection with edgers of well known type now 1n common use, and

which may be connected with'the conven tional air or steam pressure line of aniedger when used with that type of edgers wherein such air or steam line is employed.

Other objects and advantages will -be ap parent during the course of the following "de- 'scription. I V

In the accompanying drawings in which likenumerals are employed to designate like of illustrationis shown an embodiment of myv invention, the numeral 1 designates gen-, erally an edger including as a part'thereof an arbor which'is designated generally by an embodiment of my inven-- the numeral 2 and with whichis associated a plurality of saws 3, in this instance three in number. Suitably mountedwith respect to the arbor 1s a discharge pipe 4 which is provided with a plurality of nozzles 5 having their open ends, disposed adjacent the arbor. One end 6 of the pipe 4 is closed and the other end is connected by meansof a union 7, with the stem 8 of a T coupling 9, which has one end closed by means of a threaded'plug 10, and into the other end-of which is threaded the upper end of a tube ll. Upon the lower 2 end of the tube 11 is threaded a nut 12 which is formed with an externally threaded shank 13 in threaded engagement with the' upper end of a coupling 14, the lower end of which is'connected by means of a nipple 15, with a whistle valve 16. I v

Connected with the whistle valve 16 is an airline, 17, which extends from a'compressed air tank 18" suitably located. with respect to the edger and provided with, a feed pipe 19 The tank 18 is necessary only when using 'my apparatus in connection with that type of edgers Whereinsome means other than compressed air or steam isemployed for elevating v the rollers of the edgerl here compressed air or steam is available in connection with the I edger, the line 17.. is connected directly with so the compressed air or steain'supply for the edger. The trigger 20 of the whistle valve 16 is connected with a suitable cord 21 which extends along the. edger and is suspended, as

by means of a bracket or hanger 22, to be with- .in'the ready reachof the operator of the' edger. f I r p Concentrically mounted on the tube 11 is a cup 23 which is preferably cylindrical in form and through the upper wall 24 and lower wall 25 of which theexternally threaded ends of the tube 11 extend. The wall 24 is made air 7 tight where the tube 11 passes therethrough by means of a washer 26, which encircles the tube 11 and seats on the upper face of the wall 24:, and a nut. 27 which is threaded on the tube 11 to press the washer 26 firmly against the wall 24. The wall 25 is made tight where the tube 11 passes therethrough bymeans of r a washer 28 which encircles the tube 11 and is interposed between the lower face of the wall and the nut 12, the latter being tightened to firmly press the Washer 28 against the wall 25.

Extending diagonally through the upper wall 24 is an air pipe 29, the inner end 30 of which is of reduced diameter and is disposed in a plane between the transverse median of the tubular Wall 31 and the upper end thereof. The outer end opens, as at 32, into the upper portion of an oil tank 33 which is suitably disposed with respect to the edger 1 above the latter.

Extending from the lower portion of the tank 33, at a downward inclination, is an oil pipe 34, the lowerend of which is connected with the interior of the coupling 14 by means of a suitable union 35 which is threaded through the wall of the coupling 14. Below the plane of the inner end of the union 35, the wall of the coupling 14 is formed with an inwardly extending, annular flange 36, which in conjunction with a ball 3'? seated within the opening of the flange forms a valve. 37 is normally held firmly seated by means'of a compression spring 38, the respective ends of which bear against the ball 37 and the lower end face of the tube 11. Thus communication between the interiors of the upper portion of the coupling 14 and nipple 15 is normally cut off.

Communication is established between the interiors of the tube 11 and cup 23 by means of a plurality of perforations 39 through the wall of the tube 11 at that portionof the latter which lies within the cup'23. Oil may flow from the tank 33, pipe 34, coupling 14, tube 11 and perforations 39 to the interior of the cup 23 until the level of the oil reaches the opening into the reduced end 30 of the air line 29, at which time the supply of air to the tank 33 is cut off and the flow of oil stops. The wall 31 of the cup 23 is preferably transparent in order that the level of the oil within the cup may be visible.

The lower end of the T coupling 9 is formed with a thickened wall 40 which has a concen trically disposed opening 41 extending therethrough in registry with the interior of'the tube 11. The upper end of the thickened wall 40 is formed with an annular bead 42, which provides a seat for a ball 43 to form a valve. The ball 43 is normally held firmly seated by means of a compression spring 44,

l the respective ends of which bear against the ball 43 and the lower face of the plug 10. With the balls 43 and 37 in position, air is prevented from entering the tube 11 at either end thereof.

When it is desired to apply oil to the arbor 2, the operator of the edger merely pulls the cord 21 which opens the whistle valve 16 to permit air or steam to be passed therethrough from the line 17 to the nipple 15. The pressure of the air or steam in the nipple 15 lifts The ball the ball 37 olf its seat and the oil within the coupling 14 and tube 11 is forced past the ball 43 to the pipe 4, from which it is delivered through the nozzles 5 to the arbor 2. As soon as the cord 21 is released to close the whistle valve 16, the balls 37 and 43 respectively are seated by the action of the springs 38 and 44, and oil again flows from the tank 33 to the cup 23 until the level of the reduced end 30 of the pipe 29 is reached. As clearly indicated in the drawings the pipes 29 and 34 are of materially less diameter than the air lines 17 and tube 11. Owing to the small bore of the pipe 34, the flow of oil from the tank 33 while the whistle valve is open is negligible.

It is to be understood that the embodiment of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention as claimed.
